Abstract
The invention provides a pressing plate detection circuit which comprises an analog-digital converter and a processor. The analog-digital converter is connected with the two ends of a secondary pressing plate of a transformer substation, and used for converting direct-current voltage signals output by the two ends of the secondary pressing plate to digital signals. The processor is connected with the output end of the analog-digital converter, and used for judging if the digital signals are first preset signals, and if the digital signals are not the first preset signals, first control signals are output to control an external warning dice to give out an alarm. By means of the pressing plate detection circuit, manual detection of voltage of the pressing plate is not needed, and operation is simple and convenient.
